Anaerobic Digestion

Put simply, anaerobic digestion is the production of biogas after organic materials like manure and food processing waste are broken down by bacteria in an oxygen-free environment. This process results in two valuable products – biogas and digestate. The biogas is purified to separate the methane from other inert gasses. The purified methane, or RNG, is then ready for pipeline injection while the other components, such as CO2, are captured through the filtration process. The digestate is the solid byproduct created from the anaerobic digestion process and can be used to create nutrient-rich fertilizer, livestock bedding, and other soil amendments such as compost. Additionally, our facilities help to protect waterways from runoff, returning treated water back to the site for recycling. Odors are also greatly reduced since the need for open lagoons can be minimized by directing the waste stream into airtight anaerobic digester tanks.
